About comfort noise in WebRTCAudio: WebRTC endpoints MUST support [RFC3389] CN for streams encoded with G.711 or any other supported codec that does not provide its own CN. Since Opus provides its own CN mechanism, the use of [RFC3389] CN with Opus is NOT RECOMMENDED (
So you can try this option but most likely it will not be useful because Opus codec used by default.
